Plenty ... how do you think we got into this lousy tax system in the first place - and have remained in it for almost 100 years.
It's partly our fault, too, though ... and we need to correct that.
There is new data for 2001. The share of total income taxes paid by the top 1% fell to 33.89% from 37.42% in 2000. This is mainly because their income share (not just wages) fell from 20.81% to 17.53%. However, their average tax rate actually rose slightly from 27.45% to 27.50%.
